Track Brazil's Key Interest Rates

The `get_selic_meta` tool gives you the official target rate set by the monetary policy committee (COPOM). You can also pull the daily effective rate with `get_selic_diaria` to see how policy is actually playing out day-to-day. For a broader market view, `get_cdi` fetches the interbank rate, which is the benchmark for most fixed-income investments in Brazil. It's all real-time data from the source. No more stale spreadsheets.

See Where the Market Is Headed

The `get_expectativas_selic` tool is your direct line to the Focus Report. Ask Claude for market expectations and it'll pull the median, average, high, and low projections from top financial institutions. This isn't just a single number. You get the full range of forecasts, giving you a much clearer picture of market sentiment. It’s like having a summary of the Monday morning BCB report on demand.
